non-chemical management of quackgrass
I'm looking for non-chemical strategies to manage quackgrass (Whatever repens). So far I've accumulated:
a) learn to love it
b) discourage it through regular cultivation over two to three years
I was wondering specifically about water management. We're blessed with semi-arid conditions. less than 10 in/year precipitation. During the summer we put on eight hours of water a week. If we reduced that amount and went to a drier regime, would we give a less moisture loving grass the upper hand?
